Future wireless access small cells and heterogeneous deployments

Abstract

Network densification and heterogeneous deployments are key tools to satisfy future traffic-volume and end-user service-level demands. LTE release 10/11 introduced several features to enhance LTE operation in heterogeneous deployments. This will continue as part of the work on small-cell enhancements in LTE Release 12. Especially, different forms of dual-connectivity are being considered to improve overall system performance and enhance end-user experience.
